Incorrect Billing process Vodam

Incorrect billing from Vodacom

I am sending this to complain about Vodacom , they have listed my account with them as an account in areas and I have made sure that the account is up to date since I took this contract and the phone has been working since I bought it has never been disconnect but to my surprise when I call them they told me my account is in areas i pay my account its never in areas , the sad part about Vodacom is that when every you lay a complaint with them it never gets resolved the Agents are just rude and not helpful

Please assist and remove this negative status on my name from the credit bureau as its affecting badly
